Mark all these file operations as FOP_UNSIGNED_OFFSET and add asserts

dump collection.

drm/amdgpu: Init zone device and drm client after mode-1 reset on reload

In passthrough environment, when amdgpu is reloaded after unload, mode-1

include KFD, and KFD init waits until the reset is completed. KFD init
is called in the reset handler, but in this case, the zone device and
drm client is not initialized, causing app to create kernel panic.

v2: Removing the init KFD condition from amdgpu_amdkfd_drm_client_create.
As the previous version has the potential of creating DRM client twice.

v3: v2 patch results in SDMA engine hung as DRM open causes VM clear to SDMA
before SDMA init. Adding the condition to in drm client creation, on top of v1,
to guard against drm client creation call multiple times.

Currently, if the abmlevel module parameter is set, it is possible for
user space to override the ABM level at some point after boot. However,
that is undesirable because it means that we aren't respecting the
user's wishes with regard to the level that they want to use. So,
prevent user space from changing the ABM level if the module parameter
is set to a non-auto value.
